45-278 25.0mm Dia. x 40.0mm FL; Plano-Convex Lens Uncoated
The 45-278 is a Plano-Convex lens with a diameter of 25.0mm and a focal length of 40.0mm. This lens is sourced from Edmund Optics, a reputable vendor known for its high-quality optical elements. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties.
The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The lens's geometry includes a thickness of 1.39mm at the edge and 5.6mm at the center. The inner and outer radii are both 0, indicating a flat surface on one side and a curved surface on the other.
The lens's effective focal length (EFL) is 40.0mm, and the back focal length (BFL) is 36.31mm. The radius of curvature (R1) is 20.67mm. These parameters are crucial in determining the lens's performance in a specific optical system.
The lens is designed for a wavelength of 587.6nm, which is in the visible light spectrum. It is suitable for applications that require a spherical lens with a plano-convex shape and a small diameter.
